DETAILED DESCRIPTION

Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings to such an extent that the present disclosure can be easily embodied by a person having ordinary skill in the art to which the present disclosure pertains. However, the present disclosure may be implemented in various different forms, and therefore, the present disclosure is not limited to the illustrated embodiments. In order to clearly describe the present disclosure, parts not related to the description are omitted, and like reference numerals designate like constituent elements throughout the specification.

A mobile terminal disclosed herein may include a portable phone, a smart phone, a laptop computer, a digital broadcast mobile device, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation, and the like. However, it would be easily understood by those skilled in the art that a configuration according to the following description may be applicable to a stationary terminal such as a digital TV, a desktop computer, and the like, excluding constituent elements particularly configured for mobile purposes.

FIG. 1 is a block diagram illustrating a mobile terminal 100 associated with the present disclosure. Referring to FIG. 1, the mobile terminal 100 may include a wireless communication unit 110, an audio/video (NV) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, a power supply unit 190, and the like. However, the constituent elements as illustrated in FIG. 1 are not necessarily required, and the mobile communication terminal may be implemented with greater or less number of elements than those illustrated elements.

Hereinafter, the constituent elements 110-190 of the mobile terminal 100 will be described in sequence.

The wireless communication unit 110 may include one or more elements allowing radio communication between the mobile terminal 100 and a wireless communication system, or allowing radio communication between the mobile terminal 100 and a network in which the mobile terminal 100 is located. For example, the wireless communication unit 110 may include a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short-range communication module 114, a location information module (position-location module) 115, and the like.

The broadcast receiving module 111 receives broadcast signals and/or broadcast associated information from an external broadcast management server through a broadcast channel. The broadcast associated information may mean information regarding a broadcast channel, a broadcast program, a broadcast service provider, and the like. The broadcast associated information may also be provided through a mobile communication network. In this case, the broadcast associated information may be received by the mobile communication module 112. The broadcast signal and broadcast-associated information received through the broadcast receiving module 111 may be stored in the memory 160.

The mobile communication module 112 transmits and/or receives a radio signal to and/or from at least one of a base station, an external terminal and a server over a mobile communication network. The radio signal may include a voice call signal, a video call signal or various types of data according to text and/or multimedia message transmission and reception.

The wireless Internet module 113 as a module for supporting wireless Internet access may be built-in or externally installed to the mobile terminal 100. A variety of wireless Internet access techniques may be used, such as WLAN (Wireless LAN), Wi-Fi, Wibro (Wireless Broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access), and the like.

The short-range communication module 114 refers to a module for supporting a short-range communication. A variety of short-range communication technologies may be used, such as Bluetooth, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra WideBand (UWB), ZigBee, and the like.

The location information module 115 is a module for acquiring a location of the mobile terminal 100, and there is a GPS module as a representative example.

Subsequently, referring to FIG. 1, the A/V (audio/video) input unit 120 receives an audio or video signal, and the A/V (audio/video) input unit 120 may include a camera 121, a microphone 122, and the like. The camera 121 processes an image frame, such as still or moving images, obtained by an image sensor in a video phone call or image capturing mode. The processed image frame may be displayed on a display unit 151. The image frames processed by the camera 121 may be stored in the memory 160 or transmitted to an external device through the wireless communication unit 110. Two or more cameras 121 may be provided according to the use environment of the mobile terminal.

The microphone 122 receives an external audio signal through a microphone in a phone call mode, a recording mode, a voice recognition mode, and the like, and processes the audio signal into electrical voice data. The processed voice data may be converted and outputted into a format that is transmittable to a mobile communication base station through the mobile communication module 112 in the phone call mode. The microphone 122 may implement various types of noise canceling algorithms to cancel noise generated during the process of receiving the external audio signal.

The user input unit 130 may generate input data to control an operation of the mobile terminal 100. The user input unit 130 may be configured with a keypad, a dome switch, a touch pad (pressure/capacitance), a jog wheel, a jog switch, and the like.

The sensing unit 140 detects presence or absence of the user's contact, and a current status of the mobile terminal 100 such as an opened or closed configuration, a location of the mobile terminal 100, an orientation of the mobile terminal 100, an acceleration or deceleration of the mobile terminal 100, and the like, and generates a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is a slide phone type, the sensing unit 140 may sense an opened or closed configuration of the slide phone. Furthermore, the sensing unit 140 may sense whether or not power is supplied from the power supply unit 190, or whether or not an external device is coupled to the interface unit 170.

The sensing unit 140 may include a proximity sensor 141. Furthermore, the sensing unit 140 may include a touch sensor (not shown) for sensing a touch operation with respect to the display unit 151.

The touch sensor may be implemented as a touch film, a touch sheet, a touch pad, and the like. The touch sensor may be configured to convert changes of a pressure applied to a specific part of the display unit 151, or a capacitance generated from a specific part of the display unit 151, into electric input signals. The touch sensor may be configured to sense not only a touched position and a touched area, but also a touch pressure.

When the touch sensor and display unit 151 forms an interlayer structure, the display unit 151 may be used as an input device rather than an output device. The display unit 151 may be referred to as a “touch screen”.

When there is a touch input through the touch screen, the corresponding signals may be transmitted to a touch controller (not shown). The touch controller processes signals transferred from the touch sensor, and then transmits data corresponding to the processed signals to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched.

When the touch screen is a capacitance type, the proximity of a sensing object may be detected by changes of an electromagnetic field according to the proximity of a sensing object. The touch screen may be categorized into a proximity sensor 141.

The proximity sensor 141 refers to a sensor for detecting the presence or absence of a sensing object using an electromagnetic field or infrared rays without a mechanical contact. The proximity sensor 141 has a longer lifespan and more enhanced utility than a contact sensor. The proximity sensor 141 may include an optical transmission type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like.

Hereinafter, for the sake of convenience of explanation, the behavior of a sensing object being placed in proximity with the touch screen without being brought into contact with the touch screen may be referred to as a “proximity touch”, whereas the behavior of a sensing object being brought into contact with the touch screen may be referred to as a “contact touch”.

The proximity sensor 141 may sense the presence or absence of a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch velocity, a proximity touch time, a proximity touch position, a proximity touch moving state, etc.) Information corresponding to the presence or absence of a proximity touch and the proximity touch pattern may be displayed on the touch screen.

The output unit 150 may generate an output associated with visual, auditory, tactile senses. The output unit 150 may include a display unit 151, an audio output module 153, an alarm unit 154, a haptic module 155, and the like.

The display unit 151 may display (output) information processed in the mobile terminal 100. For example, when the mobile terminal 100 is operated in a phone call mode, the display unit 151 may display a user interface (UI) or graphic user interface (GUI) associated with a phone call. When the mobile terminal 100 is operated in a video call mode or image capturing mode, the display unit 151 may display a captured image, a received image, UI, GUI, or the like.

The display unit 151 may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED) display, a flexible display, a three-dimensional (3D) display, and an e-ink display.

At least one of those displays (or display devices) included in the display unit 151 may be configured with a transparent or optical transparent type to allow the user to view the outside therethrough. It may be referred to as a transparent display. A representative example of the transparent display may be a transparent OLED (TOLED), and the like. Under this configuration, the user can view an object positioned at a rear side of the mobile device body through a region occupied by the display unit 151 of the mobile device body.

There may exist two or more display units 151 according to the implementation of the mobile terminal 100. For example, a plurality of the display units 151 may be placed on one surface in a separate or integrated manner, or may be place on different surfaces, respectively.

The audio output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory 160, in a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 may output an audio signal associated with a function carried out in the mobile terminal 100 (for example, sound alarming a call received or a message received, and the like). The audio output module 152 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 153 outputs signals notifying the occurrence of an event from the mobile terminal 100. The examples of an event occurring from the mobile terminal 100 may include a call received, a message received, a key signal input, a touch input, and the like. The alarm unit 153 may output not only video or audio signals, but also other types of signals such as signals for notifying the occurrence of an event in a vibration manner. Since the video or audio signals may be also output through the display unit 151 or the audio output unit 152, the display unit 151 and the audio output module 152 may be categorized into part of the alarm unit 153.

The haptic module 154 generates various tactile effects that can be felt by the user. A representative example of the tactile effects generated by the haptic module 154 may include vibration. Vibration generated by the haptic module 155 may have a controllable intensity, a controllable pattern, and the like. For example, different vibrations may be output in a synthesized manner or in a sequential manner.

The haptic module 154 may generate various tactile effects, including not only vibration, but also arrangement of pins vertically moved with respect to a skin surface being touched, air injection force or air suction force through an injection port or suction port, touch by a skin surface, contact with an electrode, effects by stimulus such as an electrostatic force, reproduction of cold or hot feeling using a heat absorbing device or heat emitting device, and the like.

The haptic module 154 may be configured to transmit tactile effects through the user's direct contact, or the user's muscular sense using a finger or a hand. Two or more haptic modules 155 may be provided according to the configuration of the mobile terminal 100.

The memory 160 may store a program for operating the controller 180, or temporarily store input/output data (for example, phonebooks, messages, still images, moving images, and the like). The memory 160 may store data related to various patterns of vibrations and sounds outputted when performing a touch input on the touch screen.

The memory 160 may be implemented using any type of suitable storage medium including a flash memory type, a hard disk type, a multimedia card micro type, a memory card type (e.g., SD or DX memory), Random Access Memory (RAM), Static Random Access Memory (SRAM), Read-Only Memory (ROM), Electrically Erasable Programmable Read-only Memory (EEPROM), Programmable Read-only Memory (PROM), magnetic memory, magnetic disk, optical disk, and the like. Also, the mobile terminal 100 may operate a web storage which performs the storage function of the memory 160 on the Internet.

The interface unit 170 may generally be implemented to interface the portable terminal with external devices. The interface unit 170 may allow a data reception from an external device, a power delivery to each component in the mobile terminal 100, or a data transmission from the mobile terminal 100 to an external device. The interface unit 170 may include, for example, wired/wireless headset ports, external charger ports, wired/wireless data ports, memory card ports, ports for coupling devices having an identification module, audio Input/Output (I/O) ports, video I/O ports, earphone ports, and the like.

The identification module may be configured as a chip for storing various information required to authenticate an authority to use the mobile terminal 100, which may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), and the like. Also, the device having the identification module (hereinafter, referred to as “identification device”) may be implemented in a type of smart card. Hence, the identification device can be coupled to the mobile terminal 100 via a port.

The interface unit 170 may serve as a path for power to be supplied from an external cradle to the mobile terminal 100 when the mobile terminal 100 is connected to the external cradle or as a path for transferring various command signals inputted from the cradle by a user to the mobile terminal 100. Such various command signals or power inputted from the cradle may operate as signals for recognizing that the mobile terminal 100 has accurately been mounted to the cradle.

The controller 180 typically controls the overall operations of the mobile terminal 100. For example, the controller 180 performs the control and processing associated with telephony calls, data communications, video calls, and the like. The controller 180 may include a multimedia module 181 which provides multimedia playback. The multimedia module 181 may be configured as part of the controller 180 or as a separate component. The controller 180 can perform a pattern recognition processing so as to recognize a handwriting or drawing input on the touch screen as text or image.

The power supply unit 190 may receive external or internal power to provide power required by various components under the control of the controller 180.

Various embodiments described herein may be implemented in a computer or similar device readable medium using software, hardware, or any combination thereof.

For hardware implementation, it may be implemented by using at least one of application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, and electrical units designed to perform the functions described herein. In some cases, such embodiments may be implemented in the controller 180 itself.

For software implementation, the embodiments such as procedures or functions may be implemented together with separate software modules that allow performing of at least one function or operation. Software codes can be implemented by a software application written in any suitable programming language. The software codes may be stored in the memory 160 and executed by the controller 180.

Hereinafter, the method of processing a user input to the mobile terminal 100 will be described.

The user input unit 130 is manipulated to receive a command for controlling the operation of the mobile terminal 100, and may include a plurality of manipulation units. The manipulation units may be commonly designated as a manipulating portion, and any method may be employed if it is a tactile manner allowing the user to perform manipulation with a tactile feeling.

Various kinds of visual information may be displayed on the display unit 151. The visual information may be displayed in the form of a character, a numeral, a symbol, a graphic, an icon, and the like. For an input of the visual information, at least one of a character, a numeral, a symbol, a graphic, and an icon may be displayed with a predetermined arrangement so as to be implemented in the form of a keypad. Such a keypad may be referred to as a so-called “soft key.”

The display unit 151 may operate on an entire region or operate by dividing into a plurality of regions. In case of the latter, the plurality of regions may be configured to operate in an associative way. For example, an output window and an input window may be displayed on the upper and lower portions of the display unit 151, respectively. The output window and the input window may be regions allocated to output or input information, respectively. A soft key on which numerals for inputting a phone number or the like are displayed is outputted on the input window. When the soft key is touched, a numeral corresponding to the touched soft key is displayed on the output window. When the first manipulating unit is manipulated, a phone call connection for the phone number displayed on the output window will be attempted or a text displayed on the output window will be entered to the application.

The display unit 151 or touch pad may be configured to sense a touch scroll. The user may move an object displayed on the display unit 151, for example, a cursor or pointer placed on an icon or the like, by scrolling the display unit 151 or touch pad. Moreover, when a finger is moved on the display unit 151 or touch pad, a path being moved by the finger may be visually displayed on the display unit 151. It may be useful to edit an image displayed on the display unit 151.

In order to cope with a case where the display unit 151 and touch pad are touched together within a predetermined period of time, one function of the terminal 100 may be implemented. For the case of being touched together, there is a case when the user clamps a body of the mobile terminal 100 using his or her thumb and forefinger. For one of the above functions implemented in the mobile terminal 100, for example, there may be an activation or de-activation for the display unit 151 or touch pad.

FIGS. 2A and 2B are perspective views illustrating the external appearance of a mobile terminal 100 associated with the present disclosure. FIG. 2A is a front and a side view illustrating the mobile terminal 100, and FIG. 2B is a rear and the other side view illustrating the mobile terminal 100.

Referring to FIG. 2A, the mobile terminal 100 disclosed herein is provided with a bar-type terminal body. However, the present disclosure is not only limited to this type of terminal, but also applicable to various structures of terminals such as slide type, folder type, swivel type, swing type, and the like, in which two and more bodies are combined with each other in a relatively movable manner.

The terminal body includes a case (casing, housing, cover, etc.) forming an appearance of the terminal. In this embodiment, the case may be divided into a front case 101 and a rear case 102. Various electronic components may be integrated in a space formed between the front case 101 and the rear case 102. At least one middle case may be additionally disposed between the front case 101 and the rear case 102.

FIG. 8 is a view illustrating the operation example of a mobile terminal 100 according to a first embodiment disclosed herein. The mobile terminal 100 may provide a function of displaying a bulletin posted through a network service such as Social Network Service (SNS), such as Twitter or Facebook, as a list form. If the user selects an icon configured to implement a bulletin list display function, then the mobile terminal 100 displays a bulletin list on a bulletin list display screen 300. The bulletin list may be a list of bulletins stored in the mobile terminal 100 or a server.

The bulletin list display screen 300 may include a title area 310 for indicating information displayed on the display unit and a list area 320 for displaying a plurality of bulletins (bulletin list). For example, a bulletin add icon 312 to add a new bulletin may be provided on the title area 310. Images indicating the publisher of each bulletin and brief information of the bulletin may be displayed on the list area 320.

Referring to FIG. 8(b), for example, when the user performs a long touch on one bulletin 322 among the bulletins displayed on the list area 320 or selects a predetermined menu though not shown in the drawing, a work, mini-desktop or linking area 330 capable of receiving bulletins may be configured or automatically provided on the display unit. The work area 330 may be displayed at a partial region of the display unit, and may be displayed, for example, at a lower end of the bulletin list display screen 300. Furthermore, the work area 330 may be displayed to overlap with the list area 320, or may be displayed in a semi-transparent layer form to allow the user to view the overlapped bulletin.

The user may drag and drop the long touched bulletin 322 to the storage area 330, and accordingly, the mobile terminal 100 may display an icon 332 indicating the dragged and dropped bulletin 322 on the storage area 330. The mobile terminal 100 may extract a plurality of contacts from the bulletin 322 and temporarily store them in a buffer or memory device.

Referring to FIG. 8(c), if the user selects the contact add icon 312 to add a new contact in a state that the icon 332 is displayed on the storage area 330, then the mobile terminal 100 may extract a plurality of contacts from the relevant bulletin 322, and link the plurality of contacts extracted from the bulletin 322 to one another. For example, another contact may be subordinately linked to one contact extracted from the bulletin 322 to store both of them.

FIG. 9 is a detailed view illustrating a bulletin 322 shown in FIG. 8. The bulletin 322 can be transferred, replied or “tweeted” by another user other than the user 322-1 who prepares the original text. In other words, the bulletin 322 can be sent to specific users designated by the user who prepares the original text, and the users 322-2, 322-3 who can view the bulletin 322 can reply or tweet the bulletin 322 to still another user. The contact of the user 322-1 who prepares the original text and the users 322-2, 322-3 who transfer the bulletin 322 may be contained in the bulletin 322. Furthermore, the user 322-1 who prepares the original text and the users 322-2, 322-3 who transfer the bulletin 322 may be displayed in a distinguished manner within the bulletin 322.

Referring to FIG. 9(b), if the original text of the bulletin 322 has been prepared, then the user who prepares the original text or another user may prepare an add comment in response to the original text. The contact of the user 322-1 who prepares the original text and the users 322-2, 322-3 who transfer the bulletin 322 may be contained in the bulletin 322. Furthermore, the original text and add comment may be displayed in a distinguished manner within the bulletin 322.

In this manner, the contacts of a plurality of users may be contained within one bulletin, and in this case, a plurality of contacts may be subordinately connected or linked to one contact. The foregoing user interface allow one main contact to be connected to one or more auxiliary contacts subordinately connected to the one main contact.

On the other hand, when a plurality of contacts contained in the bulletin are contacts that have been stored in advance in the contact list, the mobile terminal 100 may link or associate the relevant plurality of contacts in the contact list to store them. In other words, referring to FIG. 9(c), since “Aidan” 323-1 and “Adam” 323-2 which are contacts contained in the bulletin 322 have been stored in advance in the contact list, the mobile terminal 100 can associate or link the Adam contact to the Aidan contact in the contact list to store them. However, as illustrated in FIG. 9(a), since “brlove” 322-1, “Shine” 322-2 and “Cartier” 322-3 which are contacts contained in the bulletin 322 have not been stored in the contact list (or phonebook), the mobile terminal 100 may generate contacts corresponding to “brlove”, “Shine” and “Cartier” in the contact list, and associate or link the generated contacts to store them.

FIG. 10 is a view illustrating a result to which a contact disclosed herein is connected, linked or associated. If the user selects the add icon or menu 312 to add a new contact in a state of FIG. 8(a) and/or the icon 332 indicating the bulletin 322 are displayed on the work area 330 of FIG. 9(b), then the mobile terminal 100 may link one or more auxiliary contacts 322-2, 322-3 to one main contact 322-1 from the relevant bulletin 322.

As described above, the contact list display screen 200 may include the title area 210 and list area 220, and an image and a name indicating a person corresponding to each contact may be displayed on the list area 220. Furthermore, an indicator 226 may be further displayed on the contact 224 subordinately connected to another contact to distinguish it from the another contact.

If a contact 222 which is not subordinately connected to another contact is selected, then the selected contact 222 may be designated and displayed on the recipient designation area 420 as illustrated in FIG. 13(a). However, if a contact 222 subordinately connected to another contact is selected or the email address is manually typed in for a contact associated with another contact, then the selected contact 222 may be designated and displayed on the recipient designation area 420 as illustrated in FIG. 13(c), and a contact 432 subordinately linked to the selected contact 424 may be designated and displayed on the reference area 430. Furthermore, if a send menu 412 is selected, then the mobile terminal 100 transmits a mail using the contact 424 as a recipient, and transmits the same mail using the contact 432 as a reference.

Accordingly, the user can perform multiple operations based on a contact selected by the mobile terminal 100 and a contact linked to the selected contact, respectively. Accordingly, there is an advantage that the user can transmit a mail at the same time to various contacts with a simple manipulation using a suitable scheme.

FIG. 14 is a view illustrating the process of selecting a main contact and an auxiliary contact according to a third embodiment disclosed herein.

In order to prevent the user from unintentionally performing an operation for a plurality of contacts, the mobile terminal 100 provides an interface capable of selecting only a contact desired to perform the operation among the linked contacts. As described above, the contact information display screen 250 for displaying the detailed information of the connected contact may display the contact information 252 of a selected item and another contact information 254 linked or associated to the contact information 252.

A menu or an icon 252-1, 254-1 for selecting whether the relevant contact is to be contained as a parameter of operation implementation will be further displayed. The relevant contact may be contained or not contained when the menu 252-1, 254-1 is toggled. Accordingly, the user can individually select a contact desired to perform the operation. Based on toggling the icon 252-1 and not toggling the icon 254-1, the mail in the above example will not be sent to Adam when the Aidan contact is selected.

FIG. 15 is a view illustrating the operation example of a mobile terminal 100 according to a third embodiment disclosed herein.

Referring to FIG. 15(a), the foregoing contact list display screen 200 may further display a call menu 224-1 for originating a call to each contact. When there does not exist another item associated or linked to the contact, the call menu may be merely an individual call menu requesting an individual call for the relevant item. However, when there exists another item connected to the contact, the call menu may be an individual call menu requesting a group call for the relevant contact and another contact linked to the relevant contact.

Moreover, if the call menu 224-1 is selected, then the mobile terminal 100 can request video communication for the relevant contact 224 while at the same time requesting voice communication for another contact linked to the relevant contact 224 as illustrated in FIG. 15(b). Accordingly, the mobile terminal 100 may display a group call screen 500 containing a video communication area 512 for the contact 224, and a voice communication area 514 for the another contact connected to the contact 224.

Accordingly, the mobile terminal 100 may provide an interface for performing video communication with a main contact, and performing voice communication with an auxiliary contact. There exists an advantage of solving the problem of a limited display space and network resource distribution, and providing convenience to the user when a main participant and auxiliary participants are divided in a conference.
